ABSTRACT

OBJECTIVE: Despite increasing acceptance of laparoscopy in pediatric urology, few published data are available on laparoscopic heminephroureterectomy in patients with duplex kidney anomalies. In the present study, we report our own experiences with this technique. PATIENTS AND METHODS: From August 2003 to January 2006, five laparoscopic heminephroureterectomies were performed in four girls with a mean age of 41 (9-67) months. In all cases, a non-functioning upper pole with an obstructive (n=4) or refluxing (n=1) megaureter was found. The upper pole was resected laparoscopically en bloc with the megaureter using three to four trocars. RESULTS: Mean follow-up was 42.4 (+/-7.9) months. All procedures were performed successfully without conversion to open surgery with a mean operative time of 190 (170-210)min. Blood loss was minimal and no intraoperative complications occurred. Despite chronic inflammation in the resected specimens, the patients showed no clinical signs of infection postoperatively. The average length of hospital stay was 5.6 (4-7) days. All patients were followed using duplex sonography. CONCLUSIONS: These data demonstrate that, even in infants, laparoscopic heminephroureterectomy is feasible and associated with minimal morbidity, a better cosmetic result and a shorter hospital stay compared to open surgery. The main disadvantage of the laparoscopic approach is a longer operative time. Laparoscopic heminephroureterectomy is a technically demanding procedure and should be performed only in specialized centers.

ABSTRACT

Laparoscopic pyeloplasty has been established as an effective and minimally invasive technique for treating ureteropelvic junction obstruction. Only case reports are available describing the use of laparoscopic pyeloplasty in patients with duplicated collecting systems. We report the case of a patient presenting with a short stenotic connection between the hydronephrotic lower pole system and a solitary ureter coming from the upper pole. In this patient, a side-to-side anastomosis between the renal pelvis and the ureter was successfully performed. The present data demonstrate that laparoscopic pyeloplasty is an applicable tool even in patients with upper urinary tract anomalies such as duplicated collecting systems.

ABSTRACT

Retroperitoneal lymph node dissection (RPLND) is still the most sensitive and specific method for detection of lymph node metastases of testicular cancer. Because of its invasiveness and morbidity the acceptance of open RPLND has decreased significantly resulting in a diagnostic deficit. To reduce morbidity and to increase the acceptance of RPLND, laparoscopy has been introduced. Meanwhile, clinical data with long-term follow-ups are available demonstrating the technical feasibility and oncological safety of laparoscopic RPLND. Studies comparing laparoscopy and open surgery could show advantages for the laparoscopic approach concerning blood loss, intraoperative complications and operative time. Antegrade ejaculation can be preserved in the majority of patients. In conclusion, laparoscopic RPLND is a safe method for the management of low-stage germ cell tumors with minimal invasiveness and excellent clinical results. With an increasing number of urologists trained in laparoscopy and an increasing number of published data, it may become a standard approach for low-stage nonseminomatous testicular cancer.

ABSTRACT

Congenital or acquired disorders of the urethra or ureter often require adequate tissue transfer for reconstruction. A variety of biomaterials have proved to be useful in the reconstruction of the urethra or ureter in animal models and meanwhile even clinically. Innovative tissues such as acellular matrices can be placed in the host and function as a scaffold to allow the natural process of tissue regeneration. Biodegradable scaffolds can also be used as cell transplantation vehicles for the reconstruction of urethral or ureteral tissue. One of the limitations of cell-based tissue engineering techniques however is the difficulty of growing genitourinary-associated cells in large quantities in primary cultures. It can be speculated that stem cell research might help to overcome this specific problem in the future.

ABSTRACT

The introduction of cisplatin-based systemic chemotherapy into the clinical routine has resulted in a substantial improvement of the recurrence-free and long-term survival of patients with metastatic testicular germ cell tumors. Late relapses after the completion of first-line therapy, comprising systemic chemotherapeutic treatment in combination with a complete resection of residual tumor masses visible in about 25-50% of patients, have been reported to occur in 1-5% of patients later than 2 years following the initial treatment. It has been reported that the risk for the development of late recurrence is correlated to the tumor burden at first diagnosis and/or the presence of teratomatous components within the primary testicular cancer. Second-line chemotherapy in combination with surgery, although not very well standardized, has been recommended as the most effective therapeutic regimen during the treatment of patients suffering from late recurrent germ cell tumors. Herein, we report our single-center experience with 14 patients in different clinical stages who developed late relapse after successful first-line therapy. In the present series, the risk for late relapse was not correlated to the clinical stage at first diagnosis or the presence of teratomatous elements within the primary tumor. It became evident that in selected cases chemotherapy alone can be considered a curative treatment option.

ABSTRACT

Traditionally, oncological factors have been the only ones used in the evaluation of treatment outcome for urological tumor patients. With increased diagnoses of early, curable tumors in younger individuals, health-related quality of life and functional aspects are gaining importance. Sexual and urinary function are significant aspects of quality of life, which are especially vulnerable in urological patients. New insights into the anatomy and physiology of the pelvic organs have resulted in an improvement in surgical therapy. In this article, we present the results of current experimental and clinical studies, which underline the importance of nerve sparing techniques for maintaining a satisfying urinary and sexual function in this patient population.

ABSTRACT

The rapid development of laparoscopy in urology necessitates the training of specialists to guarantee the high standard of patient care. The real-time data communication of medical information between physicians in different locations is known as telemedicine. Telementoring describes the assistance of an experienced surgeon, while telerobotics requires the use of robots. Two robots, the established AESOP and the PAKY + RCM developed at the Johns Hopkins Hospital (JHH), were used to perform a telerobotic laparoscopic renal cyst ablation in cooperation between Baltimore and Munich. The telementor maneuvered the robots over a distance of 8000 km using eight ISDN lines and a PC. AESOP moved the camera, while PAKY allowed the use of a fan retractor in the abdomen. The telerobotic operation was performed without complications or system and communication failures. Telementoring can be used for training purposes but also for consultation between specialists in emergency settings.

ABSTRACT

OBJECTIVES: To evaluate whether a laparoscopic hydro-jet device can provide a safe and effective partial nephrectomy. Partial nephrectomy is still one of the most challenging operations in urologic laparoscopy. The control of hemorrhage is very difficult to achieve with laparoscopic techniques. In open surgery, hydro-jet resection is used to cut the renal parenchyma selectively, avoiding damage to the vascular structures or collecting system.Methods. Laparoscopic wedge, as well as pole, resections of the kidney were performed in 5 pigs under general anesthesia. After exposure of the kidney, the renal capsule was incised using electrocautery. The hydro-jet was then used to dissect the renal parenchyma. In pole resections, the collecting system and central vessels were divided using an Endo-GIA. Hemostasis was achieved by electrocoagulation or clips. The dissection time and intraoperative complications were evaluated.Results. The operations were performed successfully in all animals without temporary ischemia. The hydro-jet generator allowed precise and effective tissue dissection without significant hemorrhage. The parenchymal vessels were selectively coagulated. The collecting system and central vessels remained intact and could be divided after application of the Endo-GIA. The mean dissection time was 42 +/- 6 minutes for the wedge resections and 54 +/- 8 minutes for the pole resections. CONCLUSIONS: These experimental results demonstrate the suitability of hydro-jet dissection for safe laparoscopic partial nephrectomy without temporary ischemia and with reduction of the operative trauma to the kidney. On the basis of our own experiences with other techniques, including electrocautery and laser technology for partial nephrectomy, we conclude that laparoscopic hydro-jet resection represents an interesting alternative to other techniques.

ABSTRACT

OBJECTIVES: Microsurgical ligation as well as antegrade sclerotherapy have been established in varicocele treatment. The aim of this study was to evaluate whether a combination of microsurgery and sclerotherapy can provide a safe and effective treatment of varicocele recurrence or persistence. METHODS: Nine patients with recurrent or persistent varicoceles were operated by means of the combination method. Under microscopic control varix veins were ligated selectively preserving lymphatics and arteries. Ectopic veins as a possible source for varicocele persistence or recurrence were also ligated. Finally, an intraoperative venography with subsequent sclerotherapy was performed through one of the dissected veins. RESULTS: Despite difficult anatomical situations after previous surgical interventions, the operations were performed successfully without any complications. Clinical controls showed varicocele disappearance without damage of the testis. No varicocele recurrence or persistence was observed. CONCLUSIONS: This method combines the advantages of both methods. Precision of the microsurgical technique is combined with velocity of sclerotherapy. Thus, it may represent an interesting alternative to conventional operation methods especially in the treatment of recurrent or persistent varicoceles.

ABSTRACT

BACKGROUND: Physiology of the human rhabdosphincter and its innervation are still a subject to controversy. A better understanding of rhabdosphincter function and anatomy might help to solve important urological problems like urinary incontinence. It was the aim of the present study to develop a human sphincter cell culture model for investigation of contraction mechanisms in vitro. METHODS AND RESULTS Cells were isolated from human rhabdosphincter tissue obtained from prostatectomy and cystoprostatectomy specimens. Cultured cells expressed typical features of striated muscle cells. By means of videomicroscopy with a time lapse videosystem cell contractions could be documented. Under control conditions without any contractile stimulant 8% of the cells were seen to contract. Cholinergic stimulation with 10 mM of acetylcholine induced a significant increase in contraction rate to 49%. CONCLUSIONS: These results demonstrate that cholinergic stimulation triggers contraction of cultured human rhabdosphincter cells. This model might help to understand external urethral sphincter physiology and to establish new therapies for the treatment of sphincter dysfunctions. Prostate 47:189-193, 2001.

ABSTRACT

OBJECTIVES: The initial encouraging results using 5-aminolevulinic acid (5-ALA) induced fluorescence endoscopy (AFE) have promised a procedure with an outstanding sensitivity for the detection of early stage bladder cancer. Summarized here is our clinical experience and data comprising 1012 fluorescence endoscopies. METHODS: Two hours, 30 minutes before endoscopy, 1.5 g 5-ALA dissolved in 50 mL of 5.7% sodium monohydrogen phosphate was instilled in patients intravesically. Before AFE, all patients underwent white light endoscopy, and a bladder washing cytologic specimen was obtained. A special light source provided blue light (375 to 440 nm) for fluorescence excitation. Suspicious sites were identified by their red fluorescence contrasting against backscattered blue light when observed through the long pass filter (445 nm) integrated into the telescope eyepiece. RESULTS: Two thousand four hundred seventy-five specimens were obtained (2.4 biopsies per AFE). In 552 AFEs (54.5%), neoplastic urothelial lesions were detected, in 34.2% only because of their positive fluorescence; 38.7% of these additionally detected neoplastic foci had poorly differentiated histologic features. CONCLUSIONS: AFE has proved to be a clinically feasible procedure with an outstanding detection rate for flat, urothelial, high-risk lesions.

ABSTRACT

A 51-year-old patient underwent partial nephrectomy because of a renal cell carcinoma in a horseshoe kidney. Postoperatively a remaining calix led to persistent urinoma formation. By means of superselective embolization urine extravasation was stopped successfully. This demonstrates that superselective embolization can be an effective tool in the management of complications after open renal surgery.

ABSTRACT

BACKGROUND: alpha1-adrenoceptor (alpha1-AR) antagonists, used to relieve the lower tract urinary symptoms (LUTS) in benign prostate hyperplasia (BPH) patients, are thought to act in inhibiting the contraction of stromal smooth muscle. An attempt was made using new technology to visualize and quantify the effect of alpha1-AR antagonists in a cell culture model of prostatic smooth muscle cells (SMC). METHODS: Prostatic smooth muscle cells cultured from human prostate tissue were treated with alpha1-AR agonists and antagonists. The effects on cell growth, cell contraction, differentiation status, and apoptosis were determined by means of an MTT cell viability assay, time-lapse video microscopy, RT-PCR analysis, and FACS analysis of annexin V/propidium iodide-stained cells, respectively. RESULTS: Prostatic smooth muscle cells derived from prostate tissue expressed SMC-specific markers. They showed spontaneous contractions, and phenylephrine increased the percentage of contracting cells by 3-fold. alpha1-AR antagonists inhibited spontaneous as well as phenylephrine-induced contractions. Long-term treatment with doxazosin induced differentiation tended towards a contractile phenotype, as indicated by an increase of the ratio of smooth muscle heavy chain myosin subtypes SM2/SM1. There was, however, no effect on cell growth. High concentrations of antagonist (100 microM) induced apoptosis in about 80% of the treated SMC. This effect was not cell-type-specific and was also seen in skin fibroblasts and immortalized prostate epithelial cells. CONCLUSION: In an easy-to-handle cell culture model of prostatic smooth muscle cells, the effects of alpha1-AR antagonists on cell contraction, growth, and differentiation can be investigated. The results indicate that in addition to inhibition of cell contraction, alpha1-AR antagonists have the potential to induce apoptosis.

ABSTRACT

Knowledge regarding human bladder smooth muscle cell (SMC) physiology is very limited. Only a few specific medical therapies for bladder disorders have therefore been established. The objective of this study was to develop a model for videomicroscopy of bladder SMC contractions. Cells were isolated from human cystoprostatectomy specimens and cultured in a modified EMEM medium. These cells were identified as SMCs by means of immunohistochemistry. For videomicroscopy, the culture flasks were coated with a viscous agent to allow cell contraction. Contractions were visualized by means of a cell culture microscope with a time-lapse videosystem. For cholinergic stimulation of the cells, acetylcholine, in concentrations ranging from 100 microM to 10 mM, was applied. The percentage of contracting cells within the observation field was evaluated for quantitative analysis. In control experiments without contractile stimulant 6% of the cells were observed to contract. Stimulation with acetylcholine induced a significant dose-dependent increase to 47% in contracting cells. These results demonstrated that videomicroscopy is an appropriate tool to investigate the contraction mechanisms of bladder SMCs. This model offers the possibility of studying drug effects on the human detrusor in vitro.

ABSTRACT

OBJECTIVE: Various surgical techniques have been developed to reduce the risk of bleeding during dissection of renal tissue. Water jet technology has been designed for a gentle transection of parenchymal organs. We report about first experiences with a new water jet resection device in kidney surgery. METHODS: 7 patients underwent open surgery because of renal cell carcinoma or nephrolithiasis. In tumor patients a partial nephrectomy, in 1 stone patient a nephrolithotomy, and in the other 1 a lower pole resection were performed. RESULTS: By means of water jet resection tissue was dissected effectively avoiding damage to the vascular structures, which were then ligated selectively. Resection time was between 14 and 30 min with a minimal intraoperative blood loss. No significant problem was seen postoperatively. CONCLUSIONS: The results demonstrate that water jet technology is an applicable tool for transection of renal parenchyma. It has been shown to reduce the risk of blood loss significantly compared to other techniques.

ABSTRACT

BACKGROUND: Investigations have shown an increase of leukocyte-endothelium-interaction in a variety of organs following an ischaemic insult. To elucidate the role of leukocyte-endothelium-interaction following global, cerebral ischaemia the present study was performed. METHODS: Global, cerebral ischaemia was induced for twenty minutes by four-vessel-occlusion (PULSINELLI). Leukocyte-endothelium-interaction was studied in the cerebral microcirculation using a rat closed cranial window and intravital microscopy. Leukocytes were stained intravenously using rhodamine 6G. Diameters of pial vessels, leukocyte centreline velocity and number of rolling or adhering leukocytes were determined off-line up to 2 h following global cerebral ischaemia. To confirm these results immunohistochemistry of the brain was performed. FINDINGS: Four-vessel-occlusion induced an iso-electric EEG, venular stasis and minimal rest flow in arterioles. Reperfusion yielded a significant increase of the arteriolar (p < 0.001) and a smaller increase of the venular diameters (p < 0.01). Up to 2 h after ischaemia no significant increase of the number of rolling or adhering leukocytes was measured which was confirmed by immunohistochemistry. INTERPRETATION: In contrast to other studies, in particular regarding focal cerebral ischaemia, an increase of leukocyte-endothelium-interaction in rat brain following 20 min of global cerebral ischaemia was not observed despite histological evidence of ischaemic damage. Thus in our model leukocytes seem not to contribute to the brain damage following global ischaemia.

ABSTRACT

OBJECTIVES: Different thermotherapeutic modalities such as transurethral microwave therapy or transurethral needle ablation have been developed to provide effective alternatives to surgical management of benign prostate hyperplasia (BPH). The mechanisms of thermotherapy, however, are not completely understood. We developed a model to investigate the effects of heat application on stromal cell viability and contractility. METHODS: Cells isolated from prostatectomy and cystoprostatectomy specimens were cultured in a selective medium. Temperatures ranging from 37 to 50 degrees C were applied for 1 h. Cell contraction was visualized by means of a cell culture microscope equipped with a time-lapse video system. For quantitative analysis, the percentage of contracting cells was evaluated; 10 microM of phenylephrine were applied for adrenergic stimulation of the cells. RESULTS: On immunohistochemistry and phase-contrast microscopy, these cells were identified as prostatic myofibroblasts. Incubation at 50 degrees C for 1 h in vitro induced immediate death of all cells, whereas at 45 degrees C all cells survived. At 37 degrees C 55% of the cells were seen to contract after addition of phenylephrine. Immediately after incubation at 45 degrees C contraction rate decreased to 29%, but returned to 46% 1 day later. CONCLUSIONS: With this model, it is possible to study the mechanisms of thermotherapy in vitro. The results suggest that the effects of thermotherapy are due to the induction of cell death rather than to reduced stromal cell contractility. Furthermore, the data show that treatment is probably only successful if temperatures in excess of 50 degrees C are maintained.
